Originally developed as a method to construct

high-performance gondolas for recreational balloons,

the centrifugal cast process developed into and re-

mains one of the most versatile and economical

methods of producing high-quality fiberglass tanks.

By utilizing centrifugal force to combine resin and

glass, the process provides tanks with all the mechani-

cal strength necessary for liquid storage. Centrifugal

cast tanks provide the superior chemical resis-

tance capability of a high resin-to-glass ratio wall

construction and the most aesthetically pleasing

exterior appearance in the industry. Centrifugal

cast tanks manufactured by Design Tanks, LLC are

designed to meet or exceed the design strength

requirements of ASTM D4097.

With the options of 9 different diameters (24", 30", 32", 38", 42", 48", 60", 72", and 90"), a variety of

top and bottom configurations, a range of attach-

ments, and a selection of resins, Design Tanks,

LLC can meet your fiberglass reinforced plastics

(FRP) tank needs for everything from water to

highly corrosive chemicals.
